 제목 : Fitting semiparametric accelerated failure time models for nested case–control data

 초록 : A nested case–control (NCC) study is an efficient cohort-sampling design in which a subset of controls are sampled from the risk set at each event time. Since covariate measurements are taken only for the sampled subjects, time and efforts of conductng a full scale cohort study can be saved. In this paper, we consider fitting a semiparametric accelerated failure time model to failure time data from a NCC study. We propose to employ an efficient induced smoothing procedure for rank-based estimating method for regression parameters estimation. For variance estimation, we propose to use an efficient resampling method that utilizes the robust sandwich form. We extend our proposed methods to a generalized NCC study that allows a sampling of cases. Finite sample properties of the proposed estimators are investigated via an extensive stimulation study. An application to a tumor study illustrates the utility of the proposed method in routine data analysis.

 제목 : Applications of Statistical Models in Medical Research

 초록 : In medical research, there exist a variety of data structures such as serial data sets with different follow-up intervals and points, longitudinal data sets with missing values, data sets with multiple measurements for individual subjects (for example, measurements from left and right sides), and so on. Nowadays, statistical models have become an important tool in handling a big data of medical research. In this talk, I introduce various fields of statistics for application and interest things in medical research.
